On my way home at about 10 PM I stopped around a turn on the middle of Adyala Road. It was choked with people and cars blocking the road. They were all staring up in the sky. I followed and saw a large disc with lights all around it's circumference. It wasn't that high ( Approx. 400 - 450 Feet high ). It was huge. It moved slowly, hovering on a spot. It's lover disc ( Slightly Cone shaped ) was rotating while the upper portion with the white lights all around it we moving at a relativity slower pace. After hovering at a single spot for about a few minutes it flew in the NW Direction. Couldn't trace it afterwards.
